With US spec BMWs, while you CAN get maps installed for the navi, and the language and units ARE change-able, the satellite radio and BMW assist won't work in Germany. I also hear that the radio may not work quite as well. I bought my US spec here, and I have to wait til I take it to the US before I'll be able to use these features. No BMW assist/account also means I can't use all those fun apps that let me lock the doors with my phone, etc...

Don't worry regular radio works in Europe for a U.S. spec car. However, you are correct on BMW Assist and satellite radio.
